[email protected] Some vegetables that are rarely used and/or unknown in daily menu, can represent great sources of vital nutrients to maintain the metabolic health of their consumers. Among them is Pereskia spp family, commonly known as ora-pro-nobis, "the flesh of the poor". According to RDC No. 54/2012 (BRASIL, 2012), Ora-pro- nobis can be considered a functional food due to its high protein content (approximately 25%), with high digestibility (80%), 3.35g/100g of calcium, 2.42g/100g of potassium, 1.13g/100g of phosphorus, 0.45g/100g of magnesium and 0.98g/100g of sulphur, leaf (140.36 ppm) and stem (88.75 ppm) iron.
